A giant lion with enormous fangs that roamed the Kenyan savannah more than 20 million years ago was one of the largest ever meat-eating mammals, researchers said Thursday.
A team unearthed the lower jaw, teeth and other bones of a new species, Simbakubwa kutokaafrika — Swahili for “big African lion”.
They calculated it would have weighed up to 1,500 kilogrammes and could have preyed upon the elephant-like creatures that lived there at the time.
“Based on its massive teeth, Simbakubwa was a specialised hyper-carnivore that was significantly larger than the modern lion and possibly larger than a polar bear,” said Matthew Borths, from Duke University, who co-led the research with Ohio University.
An artist’s impression of the creature shows a giant big-cat-like hunter with stripey fur and enormous fangs.
The team behind the study, published in the Journal of Vertebrate Paleontology, said Simbakubwa lived in what is modern-day Kenya around 23 million years ago, a key period in the evolution of carnivorous mammals.
They said the discovery could shed light on how supersized predators and prey evolved over millions of years around the end of the Paleogene epoch — the period where mammals grew from tiny rodents into many diverse species.
Democrats are on the verge of setting a ‘time bomb’ for any candidate who can defeat Trump
If a new president takes over the White House in January 2021, he or she may quickly find that the Democratic Party that just won control of the executive branch left a loaded gun in the hands of the Republicans, who are all too eager to use it.
That should be the takeaway from reports about the budget negotiations between the House Democrats and the Trump administration. According to Bloomberg reporter Sahil Kapur, the parties are coalescing around an agreement to raise spending by $350 billion, offset that increase somewhat with about $75 billion, and extend the debt ceiling — now set to expire in the fall — to July 31, 2021.
State Sen. Royce West enters Democratic primary to challenge John Cornyn
“I’m battle tested,” West told supporters at a campaign launch event. “You’ve seen me in battle, and I’m ready today to announce my candidacy for the United States Senate.”
The Dallas attorney has been viewed as a potential primary contender for some time now, but he remained mum publicly on his plans. In June, West met with U.S. Senate Minority Leader Chuck Schumer, D-N.Y., where he reportedly had a “positive meeting” and signaled that he was likely to throw his hat in the ring. He filed the Federal Election Commission paperwork to formally launch his bid Friday.
Former NASA flight director Chris Kraft dies at 95
NASA's first flight director Chris Kraft, who played a critical role in the American space race, has died just days after 50th anniversary celebrations for the first Moon landing, the agency said.
The 95-year-old joined NASA in 1958 and developed the planning and control processes needed for crewed space missions, creating the agency's Mission Control operations that were used to manage the first US manned spaceflight and the Apollo missions to the Moon.
"America has truly lost a national treasure today with the passing of one of NASA's earliest pioneers," said agency chief Jim Bridenstine in a statement announcing Kraft's death on Monday.
